COUPLINGFOR WOODEN PIPES.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed April 29,1905. Serial No. 258,066.

To all whom it may concern:

Be it known that I, MATTHIAs CRowTHER. a citizen of the United States ofAmerica, and a resident of Pittston,county of Luzerne, State ofPennsylvania, have invented certain new and useful Improvements inCouplings for Wooden Pipes, of which the following is a full and clearspecification, reference being had to the accompanying drawings, inwhich Figure 1 is a longitudinal sectional view of a joint constructedaccording to my invention; Fig. 2, a transverse section of the pipeadjacent to the joint; Fig. 3, a side elevation of the joint; Fig. 4:, aside elevation showing a coupling adapted for use at an angle-joint.Fig. 5 is a detailed section showing a modification.

The standard wooden pipe-sections are connected at the present time byinserting the reduced end of one of the sections into a corre spondingrabbet or socket in the end of the adjacent pipe. The objection to thismethod of connecting the pipes lies not only in the fact that thesocketed end is liable to split, but also in the fact that where it isdesired to remove one of the sections it is necessary, in view of thefact that disconnection can only be had by endwise movement of thesections, to remove several of the adjacent sections.

It is the object of my invention to obviate these objections byproviding a simple and inexpensive metallic joint for the sections, themembers constituting the joint not only embracing the adjacent ends ofthe sections, but also abutting against each other in such a manner thatany one of the pipe-sections may be removed laterally by first removingthe connecting-bolts, as more fully hereinafter set forth. To theaccomplishment of this object and such others as may hereinafter appearthe invention consists of the parts and com bination of partshereinafter fully described, and particularly pointed out in theappended claims, reference being had to the accompanying drawings,forming a part of this specification, in which the same referencecharacters designate like parts throughout the several views.

Referring to the drawings by reference characters, the letter adesignates the annular flange or tongue formed on the end of one of thesections by simply reducing the diameter thereof, and Z; a similarlyshaped and dimensioned rabbet or socket cut out of the inner wall of theadjacent section and which in the ordinary manner of connecting thesections would receive the annular projection a. Driven or screwed ontothe flange a is one member of the coupling, consisting of a ring 0,which fills the recess formed by reducing the end of the pipe and isprovided with an integral annular radial flange (Z. The other member ofthe coupling consists of a ring a, fitted into the socket b and formedintegral with an annular flange f, bearing against the end of thepipe-section and extending radially beyond it and provided with asupplemental flange g, embracing the end of the pipe and extending alongits outer surface a suitable distance.

The abutting faces of the two members are without projections, as willbe seen, so that any one section of the line of piping may be removedlaterally without disturbing the remaining sections. Suitable bolts itconnect the radial flanges at points beyond the exterior of the pipe.Any suitable packing may be clamped between the-members, this packingpreferably extending over the end of the wooden flange a. it will beseen also that the two metallic members effectually prevent the ends ofthe wood sections from splitting, and when the members are bolted uptightly they contribute materially to the stability of the pipe-line.

If desired, the inner faces of the flanges c andv g and the ring 0 maybe threaded or provided with barbs or annular serrations, as shown inFig. 5, which when the members are driven or screwed into place willbite into the wood, and thereby hold the members securely to the ends ofthe pipe-sections and avoid the necessity of extraneous fasteningdevices.

It will be apparent to those skilled in the art that various mechanicalembodiments of the invention are possible, and therefore I do not wishto be limited to the exact arrangement and construction shown.

What 1 claim, and desire to secure by Letters Patent, is-

1. In a coupling for wooden pipe-sections, the combination of twoadjoining sections, one of which is provided with an internal socket inits end, and the other of which is provided with an annular flange orprojection, a pair of metallic members abutting together, one memberconsisting of a ring fitted onto said annular projection and providedwith an annular flange extending outwardly, and the other memberconsisting of a ring fitted into the socket of the other pipe-sectionand provided with an outward extending annular flange abutting againstthe end of the section 1 and provided with a supplemental flangeemspective sections and one member consisting of a ring fitting tightlyin sald socket and provided with an outward-extending flange abuttingagainst the end of the section, this flange being provided with asupplemental flange embracing and engaging the exterior surface of thepipe, the adjacent faces of said two members abutting together and beingwithout obstructions, and means for fastening the two members togetherthrough the medium of their outward-projecting flanges.

In testimony whereof I hereunto aflix my signature, in the presence oftwo witnesses, this 27th day of April, 1905.
